3x+2y=8 y=x-6
3x+2(x-6)=8 y=4-6
3x+2x-12=8 y=-2
5x=12+8
5x=20
x=20/5
x=4 the answer is C
I would say b, it’s that’s not right it’s definitely d!! Hope this helped!!!
Answer:
99°
Step-by-step explanation:
- m∠VUT = 10x + 9
- m∠BUT = 7x - 1
- m∠VUB = 37°
- m∠VUT = ?
<u>We see that</u>
- m∠VUT = m∠BUT + m∠VUT
- 10x + 9 = 7x - 1 + 37
- 10x - 7x = 36 - 9
- 3x = 27
- x = 9
<u>Angle VUT measures:</u>
60km = 37.2823
I don't know how many decimal places you are required to round but that is the precise answer.
The number of folders and notebooks in the equation is given by 3 and 5 respectively.
<h3>How to find number of folders and notebooks?</h3>
let
- x = number of folders
- y = number of notebooks
The equation:
x + y = 8
0.50x + 1.0y = 6
From (1)
x = 8 - y
Substitute x = 8 - y into (2)
0.50(8 - y) + 1.0y = 6
4 - 0.50y + 1.0y = 6
4 + 0.40y = 6
4 - 6 = -0.40y
-2 = - 0.40y
y = -2 / 0.40
y = 5
Recall
x + y = 8
x + 5 = 8
x = 8 - 5
x = 3
